Module `dmd.backend.cgxmm`

Compiler implementation of the D programming language.

Functions

Name	Description
`cdvecfill(cdb, e, pretregs)`	Generate code for OPvecfill (broadcast). OPvecfill takes the single value in e1 and fills the vector type with it.
`cdvecsto(cdb, e, pretregs)`	Generate code for vector "store" operations. The tree e must look like: (op1 OPvecsto (op OPparam op2)) where op is the store instruction STOxxxx.
`checkSetVex(c, ty)`	Determine if operation should be rewritten as a VEX operation; and do so.
`checkSetVex3(c)`	VEX prefixes can be 2 or 3 bytes. If it must be 3 bytes, set the CFvex3 flag.
`cloadxmm(cdb, e, pretregs)`	Load complex operand into XMM registers or flags or both.
`isXMMstore(op)`	Is operator a store operator?
`orthxmm(cdb, e, pretregs)`	Do simple orthogonal operators for XMM registers.
`xmmabs(cdb, e, pretregs)`	Absolute value operator OPabs
`xmmcnvt(cdb, e, pretregs)`	Generate code for conversion using SSE2 instructions.
`xmmeq(cdb, e, op, e1, e2, pretregs)`	Generate code for an assignment using XMM registers.
`xmmIsAligned(e)`	Determine if lvalue e is a vector aligned on a 16/32 byte boundary. Assume it to be aligned unless can prove it is not.
`xmmload(tym, aligned)`	Get correct load operator based on type. It is important to use the right one even if the number of bits moved is the same, as there are performance consequences for using the wrong one.
`xmmneg(cdb, e, pretregs)`	Negate operator
`xmmopass(cdb, e, pretregs)`	Generate code for op=
`xmmpost(cdb, e, pretregs)`	Generate code for post increment and post decrement.
`xmmstore(tym, aligned)`	Get correct store operator based on type.
